In addition, the highly integrated handheld device 1 according to the present embodiment is configured to make various types of Web services available, and provides, as one of its main features, GADGET Application intensively containing various types of information and frequently used functions to the main body display screen 10. Furthermore, the highly integrated handheld device according to the present embodiment may have a function as a telephone using a normal cellular phone network, and a function as a cordless handset junctually connected to a main phone connected to a fixed phone network. Moreover, the highly integrated handheld device according to the present embodiment may be configured to be available as a portable navigation device including a GPS communication function.

The highly integrated handheld device 1 is configured to make cable LAN communication (for example, Ethernet (Registered Trademark)) and/or wireless LAN communication (for example Wi-Fi (Registered Trademark)) available for connecting to the internal network 80. In particular, the Wi-Fi (Registered Trademark) is preferably adopted in order to ensure the portability. In addition, the highly integrated handheld device 1 preferably makes, besides wireless communication (for example, Wi-Fi (Registered Trademark)), at least one of near field communication (for example, Bluetooth (Registered Trademark)), infrared communication, and communication cables available in order to communicate with the first device or the second device without going through the internal network 80.

The first devices refer to devices compliant with a predetermined standard, which can communicate with each other via the internal network 80. The first devices each include the highly integrated handheld device according to the present embodiment, the relaying device 2, a content storage device 3, and the first display device 4. The first device preferably makes, besides cable LAN communication or wireless LAN communication, further at least one of near field communication and infrared communication available.

The second devices preferably make at least one of communication through a communication cable, wireless communication, and infrared communication, for communication with the highly integrated handheld device 1.

The internal network 80 is preferably built in conformity with the DLNA (Registered Trademark) standard as the predetermined standard. In the DLNA (Registered Trademark), the Protocols of Ethernet (Registered Trademark) (IEEE 802.3) and Wi-Fi (Registered Trademark) (IEEE 802.11) are used in the link layer of the TCP/IP protocol system (Internet protocol suite). In addition, the Protocol of the TCP/IP is used in the transport layer and the network layer. However, in the present embodiment, the internal network 80 may be composed of cable LAN communication other than Ethernet (Registered Trademark), wireless LAN communication other than Wi-Fi (Registered Trademark), near field communication (for example, Bluetooth (Registered Trademark) (IEEE 802.15), ZigBee (Registered Trademark) (IEEE 802.15.4)), infrared communication, or a combination thereof.

In the case of the internal network 80 in conformity with the DLNA (Registered Trademark), the first devices are DLNA compliant devices, whereas the second devices are DLNA noncompliant devices. The highly integrated handheld device 1 itself according to the present embodiment is a DLNA compliant device. In addition, the second devices may include DLNA compliant devices besides the DLNA noncompliant devices.

While the internal network 80 has been described above which is preferably configured in conformity with the DLNA (Registered Trademark), the present invention is not limited to this configuration. The highly integrated handheld device 1 according to the present invention can also be applied to internal networks configured on the basis of other standards equivalent to the DLNA (Registered Trademark). In the present embodiment, the highly integrated handheld device 1 will be described below as being applied to the internal network in conformity with the DLNA (Registered Trademark).

The highly integrated handheld device 1 can be connected to the Internet 90 through the relaying device 2. Alternatively, the highly integrated handheld device 1 can also be connected to the Internet 90 directly or via the nearest wireless LAN access point, etc., not shown, without going through the relaying device 2 (DLNA network 80). This connection allows the highly integrated handheld device 1 to acquire the content stored in a server 8 on the Internet 90, and receive various types of Web services.

In addition, the highly integrated handheld device 1 is able to communicate via the Internet 90, etc. with various types of information terminals 9 connected to the Internet 90. This communication also allows the highly integrated handheld device 1 to provide various types of applications of the highly integrated handheld device 1 to the various types of information terminals 9. For example, the highly integrated handheld device 1 can provide the GUI for remote control of the first devices and the second devices (hereinafter, referred to as controlled devices) to screens of the various types of information terminals 9 via a Web browser. This provision allows the user, also outside the home, to control, for example, household controlled devices via the Internet 90, etc. It is to be noted that the communication between the highly integrated handheld device 1 and the various types of information terminals 9 is not limited thereto, and for example, cellular phone networks may be used for the communication.

Further, a plurality of highly integrated handheld devices 1 may be connected to the DLNA network 80. For example, the highly integrated handheld device 1 may be placed in each of multiple rooms. In addition, in a house, one of the highly integrated handheld devices 1 as a base unit may be placed in a living room or the like where the user spends a lot of time, whereas the others of the highly integrated handheld devices 1 as a cordless handsets may be placed in each of the other multiple rooms. The respective highly integrated handheld devices 1 can mutually relay various types of control signals for remote control. What is required for the highly integrated handheld devices 1 as the cordless handsets placed in the multiple rooms is the ability to relay or to transmit and receive at least various types of control signals, and other various types of functions may be thus simplified. Furthermore, remote control repeaters (not shown) for relaying various types of control signals may be placed, instead of placing the highly integrated handheld devices 1 as the cordless handsets in the multiple rooms.

The remote control repeaters are DLNA compliant devices, which receive, via the DLNA network 80, various types of control signals generated for the core highly integrated handheld device 1 to control the second devices. Then, the remote control repeaters transmit the received control signals via near field communication or infrared communication to the second devices (for example, legacy home appliances 7) which are not connected to the DLNA network 80. In particular, the remote control repeaters preferably include an infrared emitting element and an infrared receiving element in order to transmit and receive control signals to and from DLNA noncompliant devices which can receive only conventional infrared remote control signals. For example, the remote control repeaters convert IP remote control signals transmitted from the highly integrated handheld device 1 via the DLNA network, to infrared remote control signals, and transmit the remote control signals to the DLNA noncompliant devices through the use of infrared communication. Thus, in the present embodiment, control signals can also be transmitted to controlled devices which are not connected to the DLNA network 80 out of the range of access by the highly integrated handheld device 1 via infrared communication.

The various types of information terminals 9 are, for example, personal computers, cellular phones, etc. The various types of information terminals 9 are not particularly limited as long as the information terminals 9 are able to connect to the highly integrated handheld device 1 via the Internet 90, etc., and make Web browsers available. The GUI for remote control will be described later with reference to FIGS. 6A to 6E.

The relaying device 2 refers to a device for connecting the respective first devices to each other in the DLNA network 80 and further connecting the DLNA network 80 and the Internet 90. The relaying device 2 has functions such as a modem, routing, and forwarding. The relaying device 2 is, as a DLNA compliant device, preferably a wireless LAN compliant router which functions as an access point for wireless communication in the DLNA network 80.

The content storage device 3 refers to a device for storing contents. The content storage device 3 includes, as DLNA compliant devices, for example, a personal computer, a home server, a DVD recorder, a hard disk recorder, a digital camera, etc.

The first display device 4 refers to a device for reproducing and displaying contents such as moving images and still images. The first display device 4 includes, as DLNA compliant devices, for example, a device with a display function, such as a liquid crystal television, a plasma television, a projection television, a display device, and a projector.

The legacy home appliance 7 is a conventional second device (DLNA noncompliant device), which is preferably able to receive at least control signals transmitted from a remote controller via infrared communication. The legacy home appliance 7 includes, as DLNA noncompliant devices, for example, an audio device, an air conditioner, and a lighting device.

The second display device 6 refers to a device for reproducing and displaying contents such as moving images and still images. The second display device 6 includes, as DLNA noncompliant devices, for example, a device with a display function, such as a liquid crystal television, a plasma television, a projection television, a display device, and a projector. The first display device 4 and the second display device 6 are preferably HDTVs (High Definition TeleVision) which can receive high-definition television broadcast. In this case, it is preferable that in order to ensure high image quality, the highly integrated handheld device 1 and the second display device 6 include a communication interface in conformity with the HDMI (High Definition Multimedia Interface) (Registered Trademark) standards, which are connected to each other via the communication cable 70 in conformity with the HDMI (Registered Trademark) standards.

It is to be noted that while the highly integrated handheld device 1 has been described which is preferably connected to the second display device as a DLNA noncompliant device via the HDMI (Registered Trademark) cable, the present invention is not limited to this connection. What is required is the ability of the highly integrated handheld device 1 to output contents to the second display device 6 without going through the internal network 80. More specifically, the highly integrated handheld device 1 may be connected to the second display device 6 as the second display (DLNA noncompliant device) through other communication means (for example, Wi-Fi (Registered Trademark), Bluetooth (Registered Trademark)).

In other words, what is required is that the highly integrated handheld device 1 connects to the second device through any communication method so that the second device can be connected indirectly to the internal network 80 built in conformity with a predetermined standard (for example, DLNA (Registered Trademark)).

It is to be noted that while the content storage device 3, the first display device 4, etc. have been exemplified as the DLNA compliant devices in FIG. 1, the present invention is not limited to these DLNA compliant devices. As the DLNA compliant devices, other information home appliances (for example, an audio device, an air conditioner, a lighting device, a cooking device, an automatic washing and drying machine, an automatic cleaner, etc.) may be connected to the DLNA network 80.

Now, the DLNA compliant devices are classified into a Digital Media Server (hereinafter, referred to as DMS), a Digital Media Player (hereinafter, referred to as DMP), a Digital Media Controller (hereinafter, referred to as DMC), a Digital Media Renderer (hereinafter, referred to as DMR), etc. as device classes according to the DLNA guide line.

The DMS refers to a device for storing contents (digital media) in the DLNA network. The DMP refers to a device for retrieving the contents stored in the DMS to reproduce and display the retrieved contents. The DMC refers to a device for retrieving the contents stored in the DMS to reproduce and display the retrieved contents in the DMR. The DMR refers to a device for reproducing and displaying the contents transmitted from the DMS on the basis of control by the DMC.

The first display device 4 functions as the DMP or the DMR in the DLNA network 80. The content storage device 3 functions as the DMS to serve as a supply source of contents in DLNA network 80.

The highly integrated handheld device 1 can provide contents stored in its storage unit, and contents stored in external storage media (SD (Registered Trademark), a USB memory, a hard disk, etc.) connected to the highly integrated handheld device 1, to the first display device 4 which functions as the DMP on the DLNA network 80. In this case, the highly integrated handheld device 1 functions as the DMS.

In addition, the highly integrated handheld device 1 can acquire, via the DLNA network 80, contents from the content storage device 3 which functions as the DMS, and reproduce and display the acquired contents on the main body display screen 10. In this case, the highly integrated handheld device 1 functions as the DMP. Furthermore, the highly integrated handheld device 1 can retrieve contents stored in the content storage device 3 which functions as the DMS or the highly integrated handheld device 1 which functions as the DMS, and reproduce and display the retrieved contents in the first display device 4 which functions as the DMR. In this case, the highly integrated handheld device 1 functions as the DMC.

As described above, the highly integrated handheld device 1 according to the present embodiment has the function as the DMS for providing contents to the DMP on the DLNA network 80, the function as the DMP for reproducing and displaying contents acquired from the DMS on the DLNA network 80, on the main body display screen 10 of the highly integrated handheld device 1, and the function as the DMC for reproducing and displaying, on the DMR, contents retrieved by the DMS.

In addition, the highly integrated handheld device 1 can, via the DLNA network 80, acquire contents from the content storage device 3 which functions as the DMS, and reproduce and display the acquired contents on the main body display screen 10 of the highly integrated handheld device 1 and the second display device 6. In this case, the highly integrated handheld device 1 functions as the DMP, because the highly integrated handheld device 1 retrieves the contents stored in the DMS, and reproduces and displays the acquired contents. However, from the standpoint of the user, the highly integrated handheld device 1 retrieves the contents stored in the DMS, and also displays the contents on the second display device 6, which is not the DMR as a DLNA compliant device. Therefore, in this regard, the highly integrated handheld device 1 also functions as a pseudo DMC for a DLNA noncompliant device.

The highly integrated handheld device 1 can reproduce and display not only contents stored in the content storage device 3, but also contents stored in the storage unit of the highly integrated handheld device 1 or contents acquired from the server 8 via the Internet 90, on the main body display screen 10 of the highly integrated handheld device 1, and also reproduce and display the contents in the second display device 6.
